 Paecific #1 Posted : 25 October 2021 19:34:04(UTC) Rank: NewbieGroups: Registered Joined: 25/10/2021(UTC)Posts: 5Location: California Trying to plot a variety of functions and nothing shows up in the plots. I have 23 yrs of MathCad experience, but cannot figure out what Smath is looking for to plot three very simple function (See attached file).Additionally, I am not sure why an equation needs vectorized to output the answers in the normal distribution equation.Equation 1 - Normal distribution does not solve as a function until it is vectorized. Why?Equation 2 - f(x):x^3+2*x*sin(0.25) solves without vectorization but will not plot. Why?Equation 3 - f(x):vectorize(1/{σ*sqrt(2*π)}*e^{-1/2*({x-μ}/σ)^2}) solves with vectorization but does not plot (2D or X-Y plot method). Why? Smath - 2D Plots.sm (16kb) downloaded 10 time(s).

If you use the X-YPLOT plugin you need to change the variable. If instead you use SM native 2D graph then it already works as you expectsergio

Show the two other ones on same document for doctoring.2. Your sigma makes no sense !3. BTW, in Samples you should find my Stat Treasury [10 WS]Hard to find such immense Compendium.4.

Why?1. Discretize the range you want and plot ... No vectorize.2. Plot scalar directly.

Collapsed the algo at top utilities.2. Use it infinitely in-situ use [range each f(x) at will].
